The current document provides basic instructions for people that
wish to use Apache Harmony for running their Java programs. The
steps described below neither require development tools nor
necessitate compiling source code.

First, download the binary distribution appropriate to
your platform. We currently distribute binaries for Linux and
Microsoft Windows. Please follow the instructions on the
download page
to choose and download the software.

Currently, the Apache Harmony project has no formal releases of
its software.
Instead, the project offers pre-built snapshots that
are expected to run well on the platforms offered.

Once you have obtained the appropriate binary distribution,
you need to unpack it on your machine. In all cases, the
distribution will unpack into a jre
directory. Further in the document we refer to this directory
as the root directory of the distribution.

Linux Users

Use the tar program as follows:

$ tar -tzf latest-harmony-jre-linux.tar.gz

This will unpack the JRE directory tree into the current directory.

Windows Users

Use one of zip utilities available for Windows to
unpack the distribution. The three popular ones are listed
below, but anything that can handle a zip file
will work:
